NTSTATUS 0xC0000005 represents an invalid pointer reference. In 70% of cases, unstable DDR4/DDR5 secondary timings or Intel 13th/14th Gen CPU microcode voltage degradation trigger this fault.

DirectX 11 vs Vulkan launch path in Source 2

Manufacturer / Engine Standard

Valve ships Deadlock with DirectX 11 as the native Windows renderer; Vulkan remains an unsupported experimental path for this title.

Pro Benchmark Counter-Stance

Some benchmarkers report lower CPU submission overhead under Vulkan on specific RDNA3 drivers, advocating for frametime consistency.

Empirical Verification Verdict: Empirical frametime telemetry shows no reproducible advantage and a higher crash incidence under Vulkan; is a deprecated placebo for Deadlock and must not be used. Stay on DX11.

Root Cause Telemetry Analysis

Post-patch launch failures and mid-match crashes in Deadlock map to three kernel-adjacent fault domains. First, stale DirectX 11 shader cache blobs from the prior build cause pipeline state object (PSO) mismatches, manifesting as 0xC0000005 access violations during level load. Second, memory subsystem instability: DDR4/DDR5 XMP/EXPO profiles that were marginally stable pre-patch can fail under the new build's altered sub-allocator timing, producing random access violations. Third, Intel 13th/14th Gen microcode voltage margin: the updated engine's AVX-heavy asset decompression can expose insufficient Vcore margin, triggering WHEA or 0xC0000005 faults. The canonical Deadlock config resides under the citadel app structure (game/citadel/cfg and %LOCALAPPDATA%\Valve\citadel paths), not CS2's cs2_video.txt; referencing CS2 paths is a known misdiagnosis.

Step 1: Step 1: Purge Shader Cache and Verify Integrity

Eliminate stale PSO blobs and corrupted patch deltas. Run Windows Disk Cleanup targeting only the DirectX Shader Cache, then re-verify via Steam. Do not delete authentication files.

cleanmgr.exe /d C:
# Select 'DirectX Shader Cache' only, then OK
# Steam -> Deadlock -> Properties -> Installed Files -> Verify integrity of game files

Step 2: Step 2: Enforce Verified Launch Args and Config Path

Set launch options to the verified safe set. Remove all deprecated flags. Confirm the Deadlock config directory exists under the citadel structure; do not reference CS2's cs2_video.txt.

# Steam -> Deadlock -> Properties -> General -> Launch Options:
-fullscreen -nojoy

# Verified Deadlock config locations:
%LOCALAPPDATA%\Valve\citadel\ (local app data)
\steamapps\common\Deadlock\game\citadel\cfg\

Step 3: Step 3: Validate Memory and CPU Voltage Baseline for 0xC0000005

For persistent access violations, test XMP/EXPO stability and update Intel 13th/14th Gen microcode. Run a memory diagnostic and confirm the latest BIOS microcode is applied.
